Fluke 712B

Fluke 712B – Overview

The Fluke 712B is a handheld RTD (Resistance Temperature Detector) calibrator that can both measure and simulate RTD signals, making it a valuable tool for field and laboratory calibration. It supports 13 RTD types, features simultaneous 4–20 mA measurement while sourcing RTD output, and includes ramp and step functionality for linearity testing and calibration procedures. Its rugged form, magnetic mounting, and memory of previous settings make it especially convenient for on-site use.
